Intermolecular Forces (IMF) are the attractive forces between 2 molecules.
▪ strongest IMF
▪ deals with the attraction between an ion and a polar compound.
• Hydrogen Bonding
▪ 2nd strongest IMF
▪ exists anytime hydrogen is directly connected to fluorine, oxygen or nitrogen
▪ 3rd strongest IMF
▪ exists when two polar covalent compounds interact
• Dipole/Induced Dipole
▪ 4th strongest IMF
▪ deals with the attraction between a polar and nonpolar covalent compound
• London-Dispersion Forces/Van der Waals Force/Induced Dipole-Induced Dipole
▪ weakest IMF
▪ intermolecular force is found in all compounds, but it's the main intermolecular force of nonpolar covalent compounds
